Two microwave sources `S_(1)` and `S_(2)` are located at a distance of `4 lambda` from each other along Y-axis,with `S_(1)` at the origin as shown in the figure.A microwave detector D moves along the X-axis away from `S_(1)` .The first maximum is obtained for x equal to: (wavelength of the microwave is

Two coherent light sources A and B are at a distance 3lambda from each other (lambda =wavelength)The distances from A on the X-axis at which the interference is constructive are

Two coherent point sources S_1 and S_2 are separated by a small distance d as shown. The fringes obtained on the screen will be

Two coherent sources S_1 and S_2 area separated by a distance four times the wavelength lambda of the source. The sources lie along y axis whereas a detector moves along +x axis. Leaving the origin and far off points the number of points where maxima are observed is

Two coherent sources S_(f) and S_(2) (in phase with ech other) are placed at a distance of 2lambda as shown where lambda is wavelength of sound. A detector moves on line A B parrallel to S_(1)S_(2) . If detector detects maximum intensity at finite distance from O at theta = +- ((pi)/(n)) . Find n

For a particle moving along x-axis, a scaled x-6 graph is shown in figure. Mark the correct statement (s).

Two coherent sources emit light of wavelength lambda . Separation between them, d = 4 lambda . If a detector moves along the y-axis, what is the maximum number of minima observed? If the detector moves along 'x-axis beginning from S_(2) , the maximum number of minima observed is

Consider two coherent, monochromatic (wavelength lambda ) sources S_(1) and S_(2) , separated by a distance d. The ratio of intensities of S_(1) and that of S_(2) (which is responsible for interference at point P, where detector is located) is 4. The distance of point P from S_(1) is (if the resultant intensity at point P is equal to (9)/(4) times of intensity of S_(1) ) ("Given : "angleS_(2)S_(1)P=90^(@), d gt0 and n" is a positive integer")
